copyinh xbox games from start to finish

imagine i just come out of shops with a new box. i want to be able to play backed up games. however i need a chip or for the bios to be flashed and copying xbox games alot more complicated than copying ps2 games which is as simple as copying on fly with nero. people on here always talking about downloading programs onto xbox like evoloution but no one evr says how you get it from a file actually on the xbox
